2 MAIN LOGIC

2.1 Cooling

After the cooling command is sent out, the indoor fan will run at high speed for 5 seconds before it is put into operation according to the setting. Then, it is started to calculate the system load demand value. If the load is 0, the other loads except the indoor fan will not be put into operation (The water pump will run according to the pump control logic behind). If the load is >0, the EXV will be firstly opened to step X; then the indoor fan is started. After 30 seconds, the compressor is started at initial frequency 40Hz and will be maintained for 3 minutes. After that, the compressor, EXV and outdoor fan will adjust according to logic.

2.3 Heating Mode

When the heating command is sent out, it is started to calculate the system load demand value. If the

load is 0, all the loads will not be put into operation. If the load is >0, the EXV will be firstly opened to step

Y; then the outdoor fan is started. After 30 seconds, the compressor will increase its frequency to the

required initial frequency 40Hz before it started. It is started to count the time when the compressor

frequency is increased to 20Hz. After 10 seconds, the 4-way valve is energized and then the indoor fan

will run as per cold air prevention mode. The compressor will keep running at initial frequency for 3

minutes. After that, the compressor, EXV and outdoor fan will adjust according to logic.

1 INDOOR UNIT INSTALLATION

1.1 Installation of Duct Type

1.1.1 Before Installation

 After receiving the machine, please check for any transport damage. If finding any surface or

internal damage, please immediately report to the transport company or equipment company in writing.

 After receiving the machine, please check the unit and accessories in reference to the packing list.

Ensure that the model is correct and the machine is in good condition. Please also check if the specification and quantity of accessory parts are correct.

 Determine the correct handling route and methods, thus to avoid damaging the unit or causing

possible hazard. For the sake of protection and safety, it is suggested to move the unit with the packaging box. Even though it is not permitted to do like this under special occasions, do not remove the packaging box, thus to avoid loosening or falling during handling.

 Confirm if the installing foundation is solid. When this unit is to be installed on the metal section of

the building, make sure that the electrical insulation must comply with applicable standards.

 Ensure that the place of installation is far from the area where the inflammable or explosive

substances are stored, thus to avoid possible explosion or fire due to leakage.

1.1.2 Installation Site

 Ensure the top hanging piece has strong strength to withstand the weight of the unit.  The drainage pipe has convenient flow of water.  There is no obstacle blocking the return air inlet and exhaust outlet, so as to ensure sound air

circulation.

 The installation spaces required by the drawing must be ensured, so as to provide enough space for

the service and maintenance.

 The installation site must be far away from heat source, leakage of inflammable gas or smoke.  The indoor unit is of ceiling mount (indoor unit is hidden inside the ceiling).  The indoor and outdoor units, the power cable and the connecting electrical lines must be at least 1

meter from any TV set or radio. This is to avoid image interference or noise of the TV set or radio. (Even if the distance is 1 meter, noise can also exist if there is strong electric wave.)

1.1.3 Caution for Installation

1 Generally, the unit is installed indoor on ceiling. For ceiling mounting, ensure that the hangers on

ceiling have adequate strength to support the weight of the unit.

2 To meet the noise and vibration requirements, the unit shall be installed by using rubber pad

(thickness ≥20mm) and rubber connector.

3 Insert a M10 expansion bolt into the hole. Drive a nail into the bolt. Refer to the profile dimensions

drawing of the indoor unit for the distance between the holes. Refer to Figure 1 for the installation of the expansion boltas Figure 1-1-1 shows.

1.1.6 Drain Piping Work 1 Installation of Drainage Pipeline

 A drainage outlet is located at both the left and right sides of the indoor unit. After selecting one

drainage outlet, the other outlet shall be blocked by rubber plug. Bundle the blocked outlet with

string to avoid leakage, and also use thermal insulation materials to wrap the blocked outlet.

 When shipped out from factory, both the Drainage outlets are blocked by rubber plugs.

 When connecting the drainage pipe with the unit, do not apply excessive force to the pipeline at the

side of the unit. The fixing position of the pipeline shall be near the unit.

 Purchase general-purpose hard PVC pipe locally to be used as the drainage pipeline. When

carrying out connection, place the end of the PVC pipeline into the drainage hole. Use flexible

drainage tube and tighten it with thread loop. Never use adhesive to connect the drainage hole and

the flexible drainage tube. (As shown in Figure 1-1-9)

 When the laid drainage pipe is used for multiple units, the common pipe shall be about 100mm

lower than the drainage outlet of each set of unit. A pipe with thicker wall shall be used for such

purpose.

2 Testing of Drainage System

 After the electrical installation is completed, carry out the testing of the drainage system.

 During the test, check if the water correctly flows through the pipelines. Carefully observe the joints

to ensure that there is no leakage. If the unit is to be installed in a new house, carry out testing

before decorating the ceiling.

3 Matters of Attention

 The joint of Drainage Pipeline must not have leakage.

 The Drainage Pipeline shall be installed with an inclining angel of 510°, so as to facilitate the

drainage of condensate. The joints of the Drainage Pipeline must be covered by thermal insulation

materials to avoid generation of exterior condensate. (As shown in Figure 1-1-10)

Thermal insulation layer of condensate pipe
